The right direction of the development of the freeze dryer market
In recent years, continuous vacuum freeze dryers have been explored and used at home and abroad. The continuous equipment is characterized by the production of a single product with a large output and sufficient raw materials, especially for the production of pulp and granular products. Continuous equipment is easy to implement automatic control, simplifying manual operation and management, and its main disadvantage is high cost.
With the end of GMP certification, the domestic lyophilized equipment for medical use has entered the modernization stage. It has complete functions, reliable work and stable performance. It can realize online cleaning (CIP) or steam sterilization (SIP). It can meet the needs of freeze-dried production of biological products and pharmaceuticals. In contrast, the specifications of foreign freeze-drying equipment are more than domestic, with complete equipment, energy-saving structure, and continuous lyophilization equipment. In order to ensure the quality and energy saving of freeze-dried products, a combination of freeze-drying equipment and other drying equipment, such as spray freeze-drying equipment, is often used.
The development of dryers should also pay attention to energy conservation and comprehensive utilization of energy, such as the use of various joint heating methods, transplantation of heat pumps and heat pipe technology, development of solar dryers, etc.; also develop automatic control technology of dryers to ensure the realization of operating conditions; In addition, as humans pay more attention to environmental protection, improving the environmental protection measures of dryers to reduce the leakage of dust and exhaust gas will also be the direction that needs further research.
